Problems solved by technology
[0004] However, when a catheter with a tip bending angle leaves the factory, the soft tip of the catheter will gradually creep during the entire shelf life, that is, the tip bending angle will become smaller over time, until the surgeon uses it. , the angle of the head end may be too small to satisfy the operator's need for direct use

Embodiment 4
[0100] The tube fixing device in the fourth embodiment is also disposed at the distal end of the catheter protection tube 4 , and the tube fixing device also has a first channel 2001 and a second channel 2002 .
[0101] Please refer to Figures 10 to 12, the pipe fixing device includes a first fixing member 301 connected to each other and a second fixing member 302 arranged adjacent to the first fixing member 301, wherein the number of the second fixing member 302 is not limited to the fourth embodiment of the present invention. The one mentioned above can be one or more than one, such as 3, 5, 8, etc. A bayonet channel 303 is formed between the first fixing member 301 and the second fixing member 302 , for clamping and fixing the pre-shaped end of the catheter through the bayonet channel 303 .
[0102] Of course, in other embodiments of the present invention, the first fixing member 301 and the second fixing member 302 may also be non-connected or separated from each other, ...

The present invention relates to a tube fixing device and a catheter protection device comprising the same, the tube fixing device is provided with a channel for a pre-shaped section of a catheter to pass through, the channel comprises a first channel and a second channel, the first channel is used for a straight section of the head end of the catheter to pass through, and the second channel is used for a bent section of the head end of the catheter to pass through; the catheter fixing device is provided with the first channel and the second channel, the straight section of the catheter head section can penetrate through the first channel conveniently, the bent section of the catheter head section can penetrate through the second channel, and therefore it is guaranteed that the angle of the pre-shaping end of the catheter is kept for a long time and does not shrink; an operator can take out the catheter to directly use the catheter and place the catheter into a lesion position, steam plasticity of the catheter is not needed any more, and the preparation time before an operation is shortened.
Description
technical field [0001] The present invention relates to the technical field of medical devices, and in particular, to a tube fixing device and a catheter protection device including the tube fixing device. Background technique [0002] In vascular interventional therapy, in order to deliver therapeutic instruments, therapeutic agents and implants to the lesion site, it is necessary to use a combination of sheaths, guide catheters and microcatheters of different sizes to establish intravascular access. When using a microcatheter and a smaller guide catheter with a softer tip or an intermediate catheter (such as a 5F or 6F catheter) to deliver the desired location to establish access, the catheter must pass through a continuous tortuous vessel. In order to maneuver the catheter more smoothly through these tortuous blood vessels, the catheter is usually steam-shaped before it is placed in the blood vessel so that the tip has a certain bending angle. In addition, in clinical us...
